Abstract

We report on a high-energy angle-resolved photoemission (ARPES) study of the n-type high-TC cuprate, Nd_1.85Ce_0.15CuO₄ (NCCO). Our bulk sensitive results suggest a hole-like Fermi surface as seen by the so far reported low-energy ARPES studies. The soft X-ray Cu 2p core-level photoemission spectra show clear polar-angle dependence, suggesting the difference in electron states between the bulk and surface.
